[JBoss Portal] - Portal Settings Not Saving

by billw

I have been workting with both Windows and MacOS installs of JBoss 4.0.3 with Hypersonic and almost all of the admin settings do not get saved when the portal is restart. Assigning a Portlet an instance is an example of something that has not stuck. I can edit the files by hand, but that is extremlely laborious and prone (to this newbie) to error. Thoughts? I did post this on installation board originally.

[JBoss jBPM] - Re: jBPM BPEL: Process Performance and Workload ?

by alex.guizar＠jboss.com

1) Well, as you know, endpoints backed by a BPEL process are stateful. In general, you will have a process instance per request, unless two or more requests correlate to the same process instance. In this case these requests will execute the same instance. This is a consequence of the design of the BPEL language. You can expect performance similar to stateful session beans in the EJB domain. 2) In jBPM, a process instance is composed of one or more tokens. Each token represents a path of execution. Initially, a process instance contains a single token which represents the main path. When the process logic encounters an activity with more than one path of execution (the flow activity, a scope with event handlers, etc) the engine spaws one token per path. jBPM runs these paths serially to avoid starting new threads because this is forbidden in a Java EE environment. This might look bad, but in practice it is not: jBPM stops executing a path of execution when it encounters a blocking activity (these include inbound message and time-driven activities). When jBPM stops executing a path, a separate server thread must resume the execution of that path. This is where JMS is critical to the BPEL runtime: it allows for executing more than one path of the same process instance in parallel, while fully adhering to Java EE guidelines. To illustrate, consider the following example: <sequence> | <receive name="a" createInstance="yes"/> | <flow> | <sequence name="b"> | <invoke name="b1"/> | <receive name="b2"/> | </sequence> | <sequence name="c"> | <assign name="c1 /> | <receive name="c2" /> | </sequence> | </flow> | <reply name="d"/> | </sequence> The order of execution is: [thread-1] a, b1, c1 [thread-2] b2 [thread-3] c2, d Note that d executes in either thread-2 or thread-3 depending on what request arrives first, b2 or c2 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977059#3977059 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3977059

[Installation, Configuration & Deployment] - Exploded Vs Packaged mode

by pandutalli

Hi, When i deploy in Exploded mode and the server is running, I am unable to redeploy after adding a new method, I am forced to stop the server and do the redeploy, I observed struts.jar is locked. However, when i deploy in Packaged mode i am able to undeploy, deploy or redeploy without stopping the server and the changes (new methods that are added) are reflected, i am kind of confused which Mode i should use? it seems if i use Packaged mode i can modify the code (add new methods) and doesn't have to stop the server. With this observation I think Packaged benefits than Exploded? Am I correct?

[JBoss Seam] - Assigning an Actor for SEAM-jBPM integration

by bsheward

Hi, I want to use SEAM and jBPM together, which seems simple enough, but I've come to realize that setting the "actor" component is absolutely critical to getting it to work. I've read through a number of threads on this forum and seen a number of posts saying "follow the examples". The problem is that the examples (todo, dvdstore) all require a SEAM specific login process, while I am forced to use HTTP basic during testing, and CAS (a single sign-on solution, found at http://www.ja-sig.org/products/cas/). I've bought and read the JBoss SEAM: Simplicity and Power Beyond Java EE and it doesn't go into much detail on this subject. So I'm wondering, what's the best way to set the actor without needing a SEAM specific login page?

by jgilbert

OK. I hacked together a simple solution with a mock partion that seems to work fine. I'll add the details to the jira issue.

[Clustering/JBoss] - Re: ehCache 1.2 doesn't replicated data in the JBoss cluste

by bstansberry＠jboss.com

Suggest you post on an ehCache forum or the forums on hibernate.org. Maybe another user will answer you here, but I doubt that any of the JBoss folks who monitor this forum will know the answer.
